DP2 Magical Beakers

December 20th, 2012

Six beakers are arranged in a row. The first and the last beakers have some colored liquid in them. The contents of the first beaker are transferred to beaker 2 and then from beaker 2 to 3 and so on leaving a little bit behind each time. And then, when beaker 6 is reached the contents are transferred in reverse one after another just as before. Watch the video for the results.

And the questions are: Why did the color of the liquid change as it did when it was being transfer from 1 to 2 and down the line? Additional challenging question: Why didn’t the color change when the same procedure was carried out in reverse?

About Me

I am a one-time international secondary school Science/Chemistry teacher with over 15 years of teaching experience in 10 different countries spanning 5 continents. Though born a Tibetan-Buddhist in a Hindu country, I attended a Jesuit school in Nepal and traveled to four other countries for further education. Currently I spend my time doing education-related social work.

When I am not doing education-related work, I am likely to be found playing Ultimate Frisbee or the Didjeridoo, or dancing or taking photographs or hiking and trekking in the mountains or lounging on a beach!
